Watching young Dr. Cox last night on The Colbert Report talking about his new book Why E= mc2 and debunking the notion that’s been floated by some physicists that people from the future may be influencing the present in order to prevent catastrophic events associated with CERN’s particle-smashing collider from happening, I’ve been enjoying some the videos of him that are around.

Here for example, he talks about the possibility that the world may end in 2012 at the end of the Mayan “Long Count” calendar — in the process pointing out a somewhat humorous flaw in their system of calculation (that should really have been obvious).

The physics of cosmology is endlessly fascinating, so expect to see more of him popping up here from time to time.
